A cannonball is launched with an initial velocity of 15.0 m/s from on top of a 12.0 m high cliff. It lands on a 4.0 m high cliff a range of 20.0 m away. What two possible launch angles could the cannonball have to make this possible? Solve the problem using geometric vectors.

What happens to the velocity of the car when the upward pull of the cable is greater than the downward pull of gravity as the car rises toward the top?
